The posterolateral ligament of the elbow: anatomy and clinical relevance.
J Shoulder Elbow Surg
March 2024
Wrightington Upper Limb Unit, Wrightington Wigan and Leigh NHS Trust, Wigan, UK. Electronic address:
Background: The posterolateral capsule was recognized in the past as an important structure for elbow stability but was later disregarded. Two recent biomechanical studies demonstrated its role in preventing posterolateral instability, and thus it should be identified as a distinct ligament: the posterolateral ligament (PLL). This study includes 2 parts: an anatomic study of the PLL's footprint and a collection of 5 cases of pathologic lesions of the PLL.

Background: Posterolateral rotatory instability (PLRI) is a common mechanism of recurrent elbow instability. While the essential lesion is a deficiency in the lateral ulnar collateral ligament (LUCL), there are often associated concomitant bony lesions, such as an Osborne-Cotterill lesions (posterior capitellar fractures) and marginal radial head fractures, that compromise stability. Currently, there is no standard treatment for posterior capitellar deficiency associated with recurrent PLRI.

Department of Orthopedics, Xiangya Hospital, Central South University, Changsha Hunan, 410008, P. R. China.
Objective: To analyze the possible injury mechanisms in patients with dorsal avulsion fracture of the capitellum combined with medial or posterior medial dislocation of the elbow joint, and to discuss their treatment and prognosis.
Methods: Retrospective analysis was made on the clinical data of 4 patients with dorsal avulsion fracture of the capitellum combined with medial or posterior medial dislocation of the elbow joint admitted between September 2014 and September 2020, including 3 males and 1 female with an average age of 20.7 years (range, 13-32 years).
Elbow Osteochondral Allograft Transplantation and Lateral Ulnar Collateral Ligament Repair with Internal Brace: A Case Report.
JBJS Case Connect
January 2022
Department of Orthopaedic Surgery, Lenox Hill Hospital, New York, NY.
Case: A 23-year-old woman with an Osborne-Cotterill lesion and posterolateral rotatory instability (PLRI) of the elbow was treated with osteochondral allograft transplantation (OCA) and lateral ulnar collateral ligament (LUCL) repair with internal brace. Two years after surgery, she reported resolution of pain and returned to all recreational activities. She reported no mechanical symptoms and no episodes of postoperative instability.
